Job description

Job Summary

We are looking for a talented and passionate Python AI Developer to join our team in building Generative AI applications. You will work with cutting-edge technologies such as ComfyUI, Large Language Models (LLM), Retrieval-Augmented Generation (RAG), and deep model training to develop innovative, practical, and efficient AI products.

Responsibilities

  • Design and implement data processing, inference, and training pipelines using ComfyUI.
  • Integrate and fine-tune LLMs (e.g., Llama, Mistral, GPT, Claude...) for text generation, summarization, and intelligent responses.
  • Build and deploy Retrieval-Augmented Generation (RAG) systems with customized datasets.
  • Train, fine-tune, or quantize LLMs or vision models based on specific project needs.
  • Optimize inference and deployment performance on local servers, GPUs, or cloud platforms.
  • Collaborate closely with product/design teams to integrate AI-friendly features into real-world systems.
  • Contribute to the development of technical documentation, training workflows, and internal AI best practices.
Your skills and experience

Requirements

  • Minimum 2 years of experience in Python development within the AI/ML field.
  • Proficiency with ComfyUI and its ecosystem (workflow design, custom nodes, etc.).
  • Hands-on experience with open-source LLMs (e.g., Llama, Mistral) or APIs from OpenAI, Claude, etc.
  • Strong knowledge of RAG architecture and integration with vector databases (FAISS, Chroma, Weaviate, etc.).
  • Skilled in training and fine-tuning NLP/vision models using PyTorch/Transformers.
  • Experience deploying models via Docker, APIs, or simple frontends.
  • Good reading comprehension in English and the ability to research and utilize open-source repositories.

Nice to Have

  • Experience with GPU optimization (e.g., MPS, CUDA, quantization, vLLM…).
  • Previous work with voice/video AI technologies such as Whisper, TTS, LipSync, Stable Diffusion…
  • Contributions to open-source AI repositories are a big plus.
Why you'll love working here
  • A creative, open-source-friendly environment with unlimited learning support.
  • Opportunities to work on real commercial AI projects—not just demos.
  • Support for equipment, GPU server costs, and technical documentation if needed.
  • Performance-based bonuses tied to milestones and KPIs.
  • Full-salary social insurance (SHUI), 2-month probation at 85% of agreed salary
  • Lunch allowance, parking fee support, and free snack pantry.
